Amazing! Just A Little Tip 4/5

By SophiePlaysMinecraft

I Didn’t Get This Until Now But, I Got My Period When I Was Ten. It’s Almost Been A Year. I Was Born In December 10, 2006 and This Isn’t On Here. Please Add It.

The Best! 5/5

By funny Dubsmash girl

I love this app! It offers a wide range of options to select for what’s going on with your bodies. A suggestion I have is more appearance options; backgrounds and setting options to choose reminder sounds/alert within the app. I will be getting in my birth control pill soon and I know that keeping track of my period will be easy!

Accurate every month! 5/5

By JoyNicole313

Love this app! I have been using it for a year and it is accurate every month.

Needs a bit 3/5

By HkAna

I think you should definitely add breastfeeding because it totally can affect your period. Also, I think you should be able to choose what type of feminine hygiene product you are using such as a menstrual cup, tampons or pads. Different types create different symptoms, such as severity of cramps, and it would be nice to see how each on affects your body using recordings.

Perfect 4/5

By babyfairbanks

It’s great

more exercise options please 4/5

By MichChitown

amazing even for teenagers. I do wish that there was a hiking or walking option, and an agility option for your daily exercise.

Great app tells me when I’m finished baking

Seems great so far 5/5

By ariannashiine

Switching to Flo from Ovia fertility. It seems to be more accurate.

SÚPER HELPFUL 5/5

By curls and gurls

This has helped me sooo much and it helped me realize my period is so irregular, also watch out because I got a notification while one of my guy friends was using it so that was awkward.

A little improvement 5/5

By lyentte16

I wish there could be more symptoms on the app. I realized there are some normal symptoms that I get every period but can’t log it because it isn’t a option. But beside that this app is amazing been using it for years now!

Perfect little tracker 5/5

By Rissehh

My only suggestion is adding "hot flashes" to the symptom list, lol

Great app 5/5

So far so good

By kiillakaayy

Love this app! Helped me get pregnant first try! Very spot on with ovulation days!

Best app ever 5/5

By EB in Denver

This is THE best app ever. It sends amazing articles to you every day and makes you feel alright with the changes going on with you body. I’ve tried many other apps like this, but non compare to how amazing this one is

Great app! 5/5

By Hail Eynich Olenic Hole

Love the app! However, I wish there were a birth control button so your Flo isn’t messed up when you start your period

Needs something 4/5

By Partygril2011

I have just recently got this app about a couple days ago and I found it quite easy to use and that’s great. I love how you can put your symptoms in and it gives you things to read. About how to stay happy or make cramps go away. I also enjoy the fact, you can see how many hearts are on it so it makes you feel better about, how your not the only one. It’s also a super easy to read app. In the calendar it shows a lot of useful information and I love that.The one thing this app should definitely have is when you put your symptoms in, there should be a option to have like low back pain, medium back pain, or high back pain when you click on it. I also feel it should be something for food like what your craving. Something salty or sweet. I hope the more I use the app it will conform to me and my body. Overall I would recommend this to someone who is looking for a app to track what they would like to. I hope whoever reads this will get a sense to this app and how it is.
Summary- super easy to use, easy understanding and informative!
Thanks for taking the time to read have a nice day!

truth below : 1/5

By buckeyed freak

clue is better. flo is dumb

Amazing but... 5/5

By What am I supposed to our here

I love this app it’s adorable, and includes everything, but the only thing my friends and I wish it had was the ability to sync your cycle with other people and share specific things with friends etc. because other apps like these include this and I love this app more than all of the rest except for this one fact! Please include the cycle sharing option

Useful but Some Suggestions 4/5

By N-2

I've been using Flo for almost a year and it's been great to help track my cycle and symptoms. I have one suggestion: for ovulation, could there be an option for the user to confirm the ovulation date or input? Lately, the app says I'm ovulating and I don't until a few days later. In addition to that, could there be an ovulation section where the user can put in their symptoms (ovulation pain, constipation, mood, etc)? A lot happens during ovulation and it would be nice to track what's going on during this time as well as the entire cycle. And (finally), to echo what others have said about adding more mood choices. Thanks for the app!!!

feeling 5/5

By ccmjune

Fine ; thanks

usually love it but i’m annoyed right now 4/5

By Michaella715

This is the best app i have ever downloaded to track my period, etc. recently however, every time i go to add that i took my pill on time, it adds it to the next day instead of the day i selected and then sometimes 3 pills will show up for one day when i only selected one. this is very frustrating. if there is any way to fix this please do. i even checked the time and everything to make sure that wasn’t the problem.

Discussion Forums! 4/5

By Maxhorsedog

I love this app! However, we need a place to ask questions and get answers, and not just once in a while through our little news feed thing. Preferably different topics in categories, and then subtopics within.

Acurate and full of info 5/5

By Sunnyaam

I don’t often rate apps but Flo deserves a shoutout. It’s accurate, easy to use, and full of info. I use it to track my cycle mostly but the app looks like a fantastic resource for those trying to get pregs.

Symptoms 4/5

By zaynismyfather

I love this app!!! One thing I would like to see is more symptoms. For example, I get gassy and have acid reflux while PMSing, and occasional dizziness and frequent urination. Adding more symptoms or allowing you to create and save your own would be great.
I’d also love more discussions! Having an option to track if you use a tampon, cup or pad and a reminder when to change your tampon/cup would be helpful.

Love it 5/5

By Uendhsvsshc

There were so many stuff in my body that I couldn’t understand and that I was worried about. But this app helped me a lot to understand my body and symptoms. It’s very useful and I recommend this app for every girl in the world.

Loved it 5/5

By amelia rix

I can tell they took a lot of thought in this app not only does it help with tracking your period but tells you if something is wrong down there and what to if there is something wrong yes I’m a real person and I really like this app

Quality 5/5

Great period app 5/5

Amazing App (recommend for all women) 5/5

This app has helped me track my symptoms, periods, and gives me feedback on anything I tell it of. Amazing app, would give more stars if I could! :)

Great for tracking pregnancy! 5/5

By Pink4ndglossy20

I used this app to track my period and loved it. When it came to tracking my pregnancy, it was not only fun, but full of amazing support and information. I couldn’t be happier with this app 😊

Flo 5/5

By ✨🌟Paola🌟✨

La mejor de todas ❤️

Easy to use! 5/5

By Dari sweet

I’ve been having trouble tracking my period lately, so I rely on this app to help me track it! It even has “how are you feeling” type of quizzes that you can take as many times a day as you’d like. Then when you click “Done,” the app gives you tips on the emotion, or helpful reminders. I love this app!

great app 5/5

By Emma2002

pretty accurate. I like being able to track my patterns and being provided with specific insight (for example, Flo was able to point out that for the past YEAR, I have constantly logged “happy” on days 14-20 of my cycle... that’s so interesting!)

Everything is wrong 1/5

By Animepnk88

I used my days before this app and ONLY stopped using it because it stopped working and crashed a lot flo has yet to get it right even once. My periods are always the same day and start the same time every 28 days. It’s all over the place one month it’s Tuesday another month Friday then Thursday. Bye bye flo

Perfect, great to use 5/5

Helps me so much

Flo 5/5

By Lola_lolita

Great app to keep track.

Issue with O day calculation 4/5

By sockpuppet09

This app is great for tracking your period, but if you’re trying to track ovulation, it’s not as good as Fertility Friend (which is a shame, since it’s much prettier).
For example, if you get a positive opk, it will go with the next day as your ovulation day no matter what your temps show, even though you can ovulate the same day as the test or up to 48 hours later, depending on your body and when you tested. You can also get a positive opk and not ovulate, with a second LH surge coming later.
May not seem like a big deal, but it is important to get an idea of how well you timed things that month. Temping is really the gold standard in confirming ovulation. It’s fine to predict using opk data, but the o day should adjust to align with your temp rise if necessary.

Great 5/5

By Crazycatfan

I have PCOS and lost an ovary to it when I was 13, so I've been on birth control basically since starting my period. Therefore, I've pretty much always had really regular cycles and never needed a tracker. Now, I'm getting married and going to start trying for a baby, so I was given the ok to quit the birth control by my OBGYN, so I'm using Flo to make sure my cycles are still on track and to see if I'm ovulating. Love the app, it's extremely helpful. I got it to keep track of my cycles, but was so pleasantly surprised to see that it told me which days I had the highest chance of conceiving and to see encouraging stories from other women successfully getting pregnant using the Flo app with PCOS. Great app and great community. Love it.

Faster/less crashing 1/5

By iTumble1

This app takes forever to load & synch, and that’s just when it doesn’t decide to repeatedly crash.
You’ve gone through several updates & it doesn’t seem like you’re making an effort to fix this annoying issue. Logging is inconvenient enough, but having to wait for 5 minutes to be able to even do that is frustrating.

Not very accurate 3/5

By Manda55123

I got this app because the app I had used hasn’t been updated by the developer in years and it is no longer compatible with the iOS. I’ve only had this a few months and it really isn’t accurate. I have the smart predictions on as it is suppose to help better predict but even when I enter that my period came days or even a week after it was predicted it doesn’t update the guess for the following month. Because I’ve only had it a few month and have had a baby in the last year and only started getting my period back when I got the app I am willing to give it more time. My last tracker was extremely accurate to the day so I really hope this app turns out to be a good alternative

I love this app but... 3/5

Chat Insights 3/5

By Jaidenk

Ever since I did the personal quiz I haven’t had any insights allowing me to chat with others. I loved the anonymous feature and chatting with others was very fun but now I can’t anymore. Please help!
Update: I can’t stand the fact that all of my insights are filled with “Always” ads. I have already seen them multiple times. I just want my discussions back :(

So confusing 2/5

By Davish_87

I like the app but it’s so confusing trying to figure out how to tell the app your period ended. Also, there’s no way for you to track your mental health which is possible in other apps. I wish there was a way to not the last day of your period.

Great! 5/5

By Ahdjksjwh

So I just started my period the other day and I was kinda freaking out about it. I watched a ton of YouTube videos about periods and then someone mentioned an app that could help. It wasn’t this app, but my friend suggested this one to me, and I love it. So far the tracker thing hasn’t been the most helpful but that is only because I only just started and I don’t know how long mine are. But the articles are very helpful. It tells you what it is like with your symptoms and how to help it. It also tells you not to worry if you are... well worried, and it’s just amazing. I would without a doubt recommend this app.

Great app, one thing though 5/5

By Szalsza04

Hello, everything is great about this app, the period tracker is getting better and better.
But one thing drives me crazy: the app notificates me day by dayto check my statistics. I usualy do it once in a while, but aint interested in them that much,and still i see that red number on the screen.
I know it is a small problem, but still i dont like to see unchecked things.
Thank you!
